A fifth wheel system includes a fifth wheel configured to couple to a kingpin of a towed trailer. The fifth wheel includes a jaw configured to engage the kingpin, a wedge movable from an unlocked position to a locked position to urge the jaw into engagement with the kingpin, and a stop rod that sets a travel distance the wedge moves between the unlocked position and the locked position. An actuator adjusts position of the stop rod to thereby adjust the travel distance.

APPARATUSES, SYSTEMS, AND METHODS FOR DETERMINING AND VERIFYING OPERATIONAL STATES OF FIFTH WHEELS
Apparatuses, systems, and methods for determining and verifying operational states of fifth wheels. Certain methods for determining the operational state of the fifth wheel may include sensing, with at least one sensor, magnetic flux caused by a magnet on a movable component movable to lock the fifth wheel to a kingpin of a towed vehicle and determining an end position of the movable component based on the magnetic flux. The end position of the movable component is then compared to a threshold position and an operational state of the fifth wheel is determined based on the comparison of the end position of the movable component to the threshold position.

METHODS AND SYSTEMS FOR MONITORING COUPLING OF FIFTH WHEELS TO KINGPINS
A fifth wheel system includes a fifth wheel configured to couple to a kingpin of a towed trailer such that vibrations are generated when the fifth wheel couples to the kingpin. A sensor in operative association with the fifth wheel and configured to sense the vibrations and generates vibration data. A controller receives the vibration data and processes the vibration data to detect a presence or an absence of a predetermined vibration component that occurs when the fifth wheel properly couples to the kingpin. An indicator indicates proper coupling of the fifth wheel to the kingpin when the predetermined vibration component is present.

A fifth wheel for locking to a kingpin of a towed trailer includes an operating arm pivotable into and between a locked position for locking the kingpin in the fifth wheel and an unlocked position in which the kingpin can be removed from or inserted into the fifth wheel and a housing coupled to the operating arm. A pull handle is slidable in the housing into and between an extended position in which the pull handle extends from the housing and a retracted position in which the pull handle is retracted into the housing. A spring in the housing biases the pull handle towards the retracted position. When the operating arm is pivoted into the locked position the pull handle is forced into the extended position, and after the operating arm is pivoted to the unlocked position the pull handle moves to the retracted position.

A fifth wheel includes a top plate having a throat that is adapted to receive a kingpin of a trailer. The fifth wheel is equipped with a locking mechanism including a jaw slidably connected to the top plate and slidable between a closed position where the jaw blocks passage of a kingpin out of the throat of the fifth wheel and an open position where a kingpin may pass into and out of the throat of the fifth wheel. The jaw has an edge adapted to engage a kingpin positioned in the throat of the fifth wheel when the jaw is in the closed position. A release arm is pivotally attached to the top plate and the jaw. A trigger member is pivotally attached to the release arm and has a locking head. A main spring urges the jaw towards the closed position. A locking protrusion is attached to the top plate and is engaged by the locking head of the trigger member when the jaw is in the open position so as to prevent the jaw from moving into the closed position. A release member is pivotally attached to the distal end portion of the release arm.
